is it possible to make a transparent window, with no background color (with jit.window/jit.gl.render) ?
it’s for projection on a stone wall.
i have try to make a screen shot with a camera and apply it to a videoplane, but he’s difficult to bang on.
I think it is much simpler than dat: if you intend to project on a wall then my suggestion is that you create a black background in your image. Only the "bright" pixels (= object or whatever you want to show) will be seen.
Hope it helps
